Can someone help me with what is probably a ridiculously simple Fedora Linux environment init problem. I admit that I am a Linux novice - I have always used Windows, but now need to quickly do some things with Java under Linux.
I have created a shell script and it works properly when I execute it from a Fedora Linux terminal window. I know that this is the case because I placed echo statements in the script and the echoed statements show that the enviroment variables (path, etc) have changed. However, once the script ends and I type echo $PATH in the terminal session window, the environment is the same as before I executed the script. The script is as follows:
If you execute it by typing its filename, it runs in its own copy of bash. That copy gets the new environment variables; then it exits, leaving the original shell's environment untouched. Instead of executing it, you want the current shell to simply evaluate its contents; you can do that with the dot (.) command: type ". filename", and the code in the file is executed by the current shell.
